The two samples are interesting in determination of organic complex with gold and silver metals. The metal-organic complexes have been identified by using geochemical, infrared analyses and ICP-OES. The geochemical analysis was performed using 10% HCl and 1M KOH treatments of bitumen-free carbonaceous sedimentary rocks for Au and Ag extractions. Infrared spectroscopy analysis was carried out for evaluation of functional groups of organic materials and comparison spectrums between two samples. General amounts of the extracted noble metals from kerogens of both samples have Au 0.74 ppm in acidic extract and 5.23 ppm in alkaline and while Ag 0.29 ppm in acidic and 0.15 ppm in alkaline solutions were known after chemical attacks and ICP-OES measurement.

The pyrobitumen is interpreted in the work as a migrated kerogen, because pyrobitumen is also insoluble organic matter within organic solvents. The kerogens associate with abundant sulfide minerals. The first kerogen concentrates with inclusions of 2.2 % pyrite while the second one has pyrite and arsenopyrite with total amount 45.2 % in their host rocks.

The carbonaceous materials and sulfide ore minerals were analyzed in polished samples under reflected light microscopy in oil immersion (using PPL, XPL and fluorescence light); mineralogical and chemical compositions were measured using XRPD and XRF. Present analytical results indicate that the carbonaceous matter is solid bitumen (weakly soluble into acetone and no fluorescence) and it is closely associated with arsenic- and antimony-bearing sulfide minerals. The solid bitumen might be originated early before ore mineralization, because they impregnated fissure spaces before became cemented and the solid bitumen has fracture- and void-filling textures in the deposit.}, year = {2019}, pages = {1-4} } @article{MTMT:30603496, title = {A Two-step Sequential Extraction for Analyzing Hardly Accessible Precious Metals in Sulfide Ore-bearing Sedimentary Rocks}, url = {https://m2.mtmt.hu/api/publication/30603496}, author = {Junussov, Medet and Mádai, Ferenc and Kristály, Ferenc}, doi = {10.17265/2328-2193/2019.01.004}, journal-iso = {JGRE}, journal = {JOURNAL OF GEOLOGICAL RESOURCE AND ENGINEERING}, volume = {7}, unique-id = {30603496}, issn = {2328-2193}, year = {2019}, pages = {32-38}, orcid-numbers = {Kristály, Ferenc/0000-0002-0075-5994} } @inproceedings{MTMT:31879898, title = {“Review of microscopic pyrite crystals from the Triassic brownish-black marl shale in Kantavár formation of Mecsek Mountains (SW Hungary)”}, url = {https://m2.mtmt.hu/api/publication/31879898}, author = {Junussov, Medet}, booktitle = {Proceedings of the Satpayev readings innovative solutions to the traditional problem of engineering and technology}, unique-id = {31879898}, year = {2018}, pages = {1-14} }
